The invention relates to new and useful iminner face of the cover. The cover flange.l hasy L provements in containers,l and more particularan outwardly projecting bead likewise forming a 1y to a container which is capable of being herrecess at' the inner upperportion of the cover metically closed and which is easily opened'l ange. yA sealing gasket is cut into disc or ring 5. through the aid of a removableretaining wire formand is placed in the cover.

The gasket will also be forced down the side of the container wall and that it shall be yof a plastic nature so that it,

'Ihis sealing gasket may be of any desired construction. y It may be pre-formed or it maybeflowed onto the cover and formed thereon.

sealing of the cover to the container. A

When the cover has been forced intoV tight sealing contact with the container the lower edge I4 of the flange or cover is bent or spun underneath a retaining wire I6, and this will hold the` cover securely locked to the container body. Any upward pull of the lower .edge of the cover flange is restrained by thekretaining wire, and

the retaining wire isrmly seated'in the pocket or recess formed by the bead. 'I'here must be a Abending of the parts in order to in anyway ree fens the same, and these ltwo features together,

lease the seal ofthe cover to the container body.

Inasmuch as the retaining wire is surroundedv circumferentially, nearly-180 by the container body, and is likewise surrounded 180 by ther coverflange, a very rm locking grip isA obtained.

Furthennoreythe upper edge of the containerl body nests in the recess IIIv on the topI of the cover to a certain extent when the cover is sealed tovthe container body, and this will hold thebody Wall from any vinward deection. The ruling of the upper edge of the body wall also stifcooperate to make a very rigidwall .in the yregion where the retaining wire is housed in the groove formed `by the inwardly projecting beady 6. The

retaining wire I6 has one endthereof bent down-l wardly at Il' and extended to form a handle portion I8 which may be gripped for withdrawing the retaining wire. The edgeof the collar which is turned underneath the retaining wire will cross the downwardly rbeni; portion I1 kand otherwise it will be turned underneath-the Vretaining wire substantially throughout the entire circum- The handle end I8V of the retaining wire will lie,/therefore,along vference of the container,`

parallel with the wall of the container, and the bent outwardly releasing the retaining wirexnore` and more until it is finally entirely released when the cover Vflange will then be also `entirely rev-lv leased from its locked engagement with the container body.

As shown in the drawing, thetop 9 of the cover is provided with an opening I9 therethrough which is located centrally of the cover. The

gasket, which is in disk form, is also cut away throughout the extent of -A this opening. Placed against the under face of the gasket is a disk or Vpanel 20, preferably of malcalite, which is transparent` and which will stilly cover and seal thev opening. The'disk or panel 2,8 extends all the way across the container and over the top of the rounded edge of the wall of the container, so that the gasket will be rmly gripped between the cover topand this macalite disk. Inasmuch as It is essential, however,-

In order-to open the `containerA this handle end of the 'retaining wire is grasped 'and pulled downward in agdirection substantially y directly over the body wall of the container produces a very tight hermetic seal. The contents of the container can be inspected or viewed through this opening I8. .l

From the above it will be apparent that a container has been provided which may be hermetically closed through the aid of a cover and a vsea-ling gasket and a retaining wire, which retainnggwire may be easily removed for breaking theseal and releasing the cover.

It is obvious that minor changes in the details ofconstruction may be made without departing from the spirit of the invention as set forth in the ,appendedclaima Having thus described the invention, what I claim as new and desire to secure by Letters Patent,is:- f y 1.
